Distillation Flask – Long Neck (HS017) 100-500ml

Borosilicate 3.3 Laboratory Flask | 100–500 ml

The HS017 Long-Neck Distillation Flask is a precision laboratory vessel designed for distillation, reflux, heating, and solvent separation applications. Manufactured from Boro 3.3 borosilicate glass, this flask offers excellent resistance to thermal shock and chemical attack, making it suitable for routine laboratory work and research environments.

The elongated neck provides improved vapour guidance and easy integration with condensers, adapters, and other standard glassware components, supporting efficient and controlled distillation setups.

Available in 100 ml, 250 ml, and 500 ml capacities, this flask is ideal for analytical labs, teaching facilities, and R&D workflows.
